Abstract: A walk power mower has a mower deck that encloses a pair of rotary cutting blades with the grass clippings from the blades being discharged through a rearwardly extending grass discharge tunnel in a rear bagging mode of operation. The blades are powered by a timed drive system that is carried by a horizontal apron that is part of a cast aluminum engine mount. The engine mount and the apron are bolted to a stamped steel deck shell that forms the cutting chamber in which the blades rotate. The mower has a side discharge mode in which a side discharge chute is releasably mounted over a side discharge opening. The chute carries a flow cutoff baffle having an inwardly protruding inner end that sticks through the side discharge opening to intercept and direct the clippings out through the side discharge opening and through the chute in the side discharge mode.

Abstract: A disc mower conditioner utilizing a modular disc cutterbar to sever standing crop material by impact action. The side sheets of the disc mower conditioner are provided with a rolling crop divider that can be an optional attachment. The rolling crop divider is constructed as a series of overlapping rolling coulters mounted to the side sheet by bearings to enhance the rolling operation of the coulters. The rolling coulters effectively divide the crop material to direct tall and entangled crops into the header to be severed by the rotating knives. The coulters are arranged in a trailing orientation to present a curved leading edge that is highly effective in directing tall, entangled or viney crops downwardly into engagement with the adjacent disc cutter.

Abstract: A pull-type mower conditioner includes a crop harvesting header vertically movable relative to the frame of the mower conditioner between a raised transport position and a lowered operative position, a lift mechanism to effect the movement of the crop harvesting header relative to the frame, and a transport latch mechanism to control the locking of the lift mechanism in the transport position. The transport latch mechanism has a biasing lever operably positionable between locking and unlocking positions. An extension spring is connected to the biasing lever to bias the lever in the selectable positions. The transport latch will not engage whenever the header is moved to the transport position to avoid an obstacle unless the biasing lever is moved to the lock position. Once the biasing lever is adjusted to bias the transport latch into the lock position, the raising of the header into the transport position will actuate the transport latch and lock the lift mechanism from returning the header to the lowered position. The lift linkage incorporates a cam mechanism that serves as an upper flotation limit under normal operating conditions and automatically converts into a device for securing the header in the transport position when the header is moved into the transport position.
